Abstract: As instruction and learning gain new dimensions in today's world due to the proliferation of information and communication technologies (ICTs) - multimedia, the Internet or the Web, as a medium to enhance instruction or as a replacement for other media-, education becomes independent of time and space. Consequentially, learners and instructors can utilize new modes of learning and communication due to the proliferation of information and communication technologies (ICTs). One of these new modes of learning and communication to support a full range of teaching and learning activities conducted by educational institutions is Moodle which facilitates online content creation and collaboration and entails various social and communication tools that support teacher-student, student-student, and teacher-teacher interactions. In the present paper, our main purpose is to demonstrate the way of using the Moodle in the education process at the Gaia Vocational School (GVS). !
The platform was characterized and promoted among the School members of GVS. The impact of this new platform (e-Courses) on the learning institution activities was evaluated through an online questionnaire, which showed high satisfaction levels with e-Courses.

Abstract: While working out an architectural research on a quarter of buildings called the "Courtyard of Miracles" in Athens, the Directorate of Restoration of Modern and Contemporary Monuments revealed and studied certain 19th century methods of environmental cooling, heating and insulating the houses. Consequently, the Restoration Service faces a double challenge: it has to preserve the traditional ways of environmental architecture and propose contemporary methods of maintaining the thermal balance, taking into account the re-use of the whole quarter as a museum. New suggestions should not offend the traditional ones, but, on the contrary, they should bring them out.

Abstract: Old housing areas, such as the historic centres of most European cities, are objects of architectural or cultural interest, since they include a large number of historic buildings and monuments dating from various historic periods. Such monuments together with their access and surrounding areas are often a unified complex, whose spatial design and operation can be fully recorded and documented by means of a 3D Geographical Information System. The representation of all historic multiple impact and the various phases through years starting from the more recent up to the most old objects can be easily achieved by recording the current condition of the buildings and other historic monuments, the topography and planning characteristics of the surrounding area, and by combining these data with a variety of quality information, such as images, videos, old maps and city plans and other available data.

Abstract: The performance of web-based software systems is one of the most important and complicated consideration. With the help of a proper performance model and an appropriate evaluation algorithm, performance metrics can be predicted. The goal of our work is to introduce and verify an improved multi-tier queueing network model for web-based software systems. In our work, an evaluation and prediction technique applying dominant factors in point of response time and throughput performance metrics has been established and investigated. The Mean-Value Analysis algorithm has been improved to model the behavior of the thread pool. The proposed algorithm can be used for performance prediction. The convergence and limit of the algorithm have been analyzed. The validity of the proposed algorithm and the correctness of the performance prediction have been proven with performance measurements.

Abstract: This paper presents the study of flux, torque and speed estimation of an induction machine drive. The d-q model of the induction machine based on space vector theory is used to determine the various matrices of the state space representation of the system. The modeling and simulation is carried out by using the MATLAB/Simulink software. Five estimators are analyzed using as inputs different machine voltage, current, or speed measurements. First, two estimators are derived by direct synthesis from state equations. Then, two of the major types of observers, a Luenberger observer and an optimal extended Kalman filter (EKF) are investigated. Finally a trained neural network is used to estimate the speed of the induction machine drive. The performances of all estimators are presented and good results were obtained for the Luenberger and the EKF, even in the presence of the system and measurements noise in the latter case.

Abstract: Nowadays, it is frequent that engineering companies use Internet as the main working environment for the complementary services offered to their customers. Furthermore, Internet allow the development of powerful tools dedicated to the remote maintenance, on-line supervision and performance optimisation of the industrial machinery. In this paper, a extensive set of complementary services via Internet denominated IngeRASTM that provide rapid and effective access to industrial machinery, supplied by the Basque company Ingelectric S. A., is described. Additionally, a new remote system dedicated to the hardware-in-the-loop (HIL) experimentation concerning the optimisation of the performance of industrial controllers installed by the company, is presented. Such a system, now under construction, exploits the rapid prototyping strategy of real-time computer controlled systems and is expected to be added to IngeRASTM in the near future in order to be used remotely by the en!
gineers by means of virtual instrumentation.

Abstract: The original procedure for identification of nonlinear continuous time systems with time variable parameters based on distribution theory, developed by the authors in a previous paper, is now deeply analysed. The fundamental of distribution theory applied to nonlinear system identification purposes is clarified. There are considered nonlinear dynamical systems described by differential equations whose right part is a rational function. Some of the system parameters change in time according to unknown laws. These laws are expressed as finite degree time polynomials whose parameters are included in the set of parameters to be identified. Considering functionals weighted by polynomials, it is possible to transform a time variant differential system of equations to an algebraic system in unknown parameters. The hierarchical structure identification method for rational expressions, is extended to time variant systems. An application for parameter identification of a was!
tewater biodegradation process, considering time variant yield coefficients is presented. An application for parameter identification of a wastewater biodegradation process, considering time variant yield coefficients is presented.

Abstract: This paper proposes and simulates a new ad hoc multicasting routing protocol called Modified On-Demand Multicast Routing Protocol (MODMRP). The MODMRP is based on On-Demand Multicasting Routing Protocol (ODMRP). MODMRP suggests two approaches aimed to reduce the service traffic; the local detection of routes and the information usage on the channels condition during the route information update timer values. The goal of MODMRP is to improve packet delivery efficiency. Through a course of simulation experiments, the MODMRP is compared to the ODMRP in reference to number factors such as Ratio of Packets Delivery and transmission delays. The Simulation results show an increase in the percentage of delivered multicast datagram on an average of 2% and a routing overhead costs decreased on average of 20.5% when compared to ODMRP.

Abstract: Visibly pushdown languages are a subclass of context-free languages that is closed under all the useful operations, namely union, intersection, complementation, renaming, concatenation, and Kleene star. The existence of a fully compositional process algebra based on such languages requires that these languages be also closed under slightly more esotheric operations, namely prefix, shuffle, and hiding. We prove here all these closure properties. We also give the semantics of visibly pushdown automata in terms of labelled transition systems. In effect, we prove the existence of a fully compositional process algebra based on visibly pushdown languages, and we also lay the foundations of such an algebra. We also find that, in addition to the pumping theorem borrowed from context-free languages, visibly pushdown languages have some additional pumping properties, which can have consequences on the recursive constructs of a visibly pushdown algebra.

Abstract: In this paper, we propose a design method of the narrow band FIR filter in a Fluency signal space. As a result, we can make superior narrow band FIR filters than ordinary one. While an FIR filter has advantages that it is stable and can realize perfect linear phase, its transfer function can be of higher order according to desired accuracy. One of such difficult classes that indeed requires lots of multipliers is the narrow band filter. In proposed method, it is possible to design a narrow band FIR filter with multipliers much less than Remez method, a typical conventional method. In the first step of the proposed method, a pair of mother filters that are basic for the desired filter are defined. In the next step, scaled filters of the mother filters will be taken. Finally, we take an appropriate cascade connection of the scaled filters and make it the approximation model of the desired characteristics of narrow band FIR filter. By a numerical experiment, the propo!
sed method is shown to be supeior to Remez method, as stated above.

Abstract: In recent years, there has been a surge of interest in the development of Information and Communication Technologies (ICT), especially in the realm of education. A large portion of current ICT work focuses on remote control devices that use HTTP browsers. This paper presents the phases to develop a system that allows multiple users the access to a multiple real electronic circuits using any HTTP browser. With this aim, specific hardware and software have been designed and incorporated to a server-computer which includes a data acquisition card. The novel feature of this work is that the user has in a unique environment with the descriptions of the circuits to study, the possibility to work with real measurements and the necessary laboratory instruments to analyze the circuit signals. The prototype employed analyzes basic analog electronic circuits in order to check out the practical viability of this type of remote control system. Once functionality is demonstrated!
, the prototype can be used as an applicable model for remote controls in any type of real system. The communication protocols, control programs and user interfaces that allow the data transmission and the hardware access have been programmed using Virtual Instruments (VI) designed with LabViewâ – Laboratory Virtual Instrument Engineering Workbench. LabViewâ is a graphical programming language widely adopted throughout industry, academia, and research laboratories as the standard for data acquisition and instrument control software. The front panel of the VIs that guides the user through the system is embebed in his or her web browser like an ActiveX Control. In addition, the user has the possibility to pass information from the HTML browser to the application in the Server in order to study the behaviour of the composed circuits.

Abstract: Tourism industry represents the sector with the highest development at global level. Cultural tourism became an important trend at international level; 60% of the European tourists are interested in cultural discovery. Romania's tourism potential remained largerly unexplored during the last 17 years due to the attention given to traditional tourism products: sun tourism at Black Sea and ski tourism during the winter. In 2006, WTTC recommended cultural and heritage tourism to become an important tourism product for Romania. The attraction points are numerous, various and interesting. Tourism stakeholders can create independent and complex products in order to promote Romania as a cultural tourist destination. The concentration of around 47% of total tourist arrivals in the main 40 Romanian cities, where the most important cultural attractions and events are concentrated, indicates that cultural tourism can be either a distinct product, or can complete other forms of!
urban tourism. Cluj-Napoca is one of Romania's most important cities from the number of citizens' point of view, also due to its business environment and cultural attractiveness. Cluj county stands on the sixth place in Romanian destinations classification, taking into account the number of lodging capacities, but Cluj-Napoca - the municipality of the county - is situated on the third place after Bucharest and Timisoara using the same criteria. The paper identifies the main tourist segment on the market and analyses the perception of tourists regarding Cluj-Napoca as a tourist destination. We used for our study personal interviews based on a questioner applied to a representative sample and empirical research analysing statistical data and other available information about the destination.

Abstract: In this paper, we present a case study to discuss the internet usages of primary school students and the exploring capabilities of using internet on regional culture course. 226 students of grade five from a primary school in Taiwan were selected as samples. We designed a questionnaire to analyze the internet usages and behaviors of these sampled students including time spending in internet, frequency, location, and reason of using internet, internet activity, and recognition of internet functionality. We designed questions for the regional culture test and conducted experiments to analyze the relationships between the internet usages and the scores of the regional culture test. Furthermore, we analyzed the relationships among students¡¦ backgrounds, academic achievements, internet usages, and the scores of the regional test. Concluding remarks and the suggestions for future studies are also provided at the end of this paper.

Abstract: In this paper, we propose a case study to compare the learning difference on a Computer added Drafting (CAD) course between traditional learning and e-learning. The learning materials for the e-learning were designed in Shareable Contents Object Reference Model (SCORM) standard. Seventy-four students from a vocational high school in Taiwan attended the experiment. These students were divided into two groups: the control group and the treatment group. The control group was provided with traditional learning in a regular classroom. The treatment group utilized an e-learning platform to conduct learning activities. The experimental results show that the learning performance between the traditional learning and the e-learning on CAD course is not different. Finally, a survey was also conducted to realize the users¡¦ satisfaction of using the e-learning course.

Abstract: The main goal of this article is to develop a virtual educational environment model which makes learning easier by using collaboration (and extension, team-research model) as a form of social interplay. The model represents a universe where human agents interact with artificial agents (software agents). Considering the vision of the system, it can be classified among advanced systems for it is client-oriented (student) and provides value added educational services, due to the collaborative learning attribute. The model proposes an original architecture where elements of the socio-cultural theory of collaborative learning are assigned to the artificial intelligence components (the multi-agent system). The expected results are: conceptual models (agents, learning and teaching strategies, student profiles and group profiles, communication between agents, negotiation strategies and coalition formation), software entities, and a methodology to evaluate the performance o!
f eLearning systems.

Abstract: In view of finding out the size of and demand created by clubfoot in our country, we have designed, created and implemented an integrated communication system for the congenital idiopathic clubfoot. On the basis of the information and data in this system, the parents have an information resource at their disposal that enables them reach a decision concerning the way in which the deformity of their child could be treated. The integrated informational system for the congenital clubfoot has two components: the medical component – dedicated to the medical staff – and the informative component – dedicated to the parents and children suffering of clubfoot. The system also, will generate positive economical implications.

Abstract: This paper presents a 1x4 array antenna using asymmetric T-shaped slit loaded microstrip antenna (MSA). The antenna consists of four MSAs align vertically on a dielectric substrate and ground plane. This antenna will be utilized in WLAN applications as the commercial panel antenna. A modified array configuration is proposed to further enhance the antenna radiation characteristics and usable bandwidth. The desired patterns of array are improved by adjusting the array element spacing from lamda/2 down to lamda/3. Moreover, alternating of the slit loads positions on each side of some patches in array can control the directive patterns to be symmetric shapes. The measured results of the radiation pattern, input impedance, return loss, VSWR, directive gain, and are also conducted for verification of the IE3D-based simulated results. With good agreement between the simulated and measured results and accordance of the requirements, therefore, this proposed panel antenna i!
s appropriate for the wireless applications.

Abstract: In this paper, we use decision trees to establish the decision models for insurance purchases. Five major types of insurances are involved in this study including life, annuity, health, accident, and investment-oriented insurances. Four decision tree methods were used to build the decision models including Chi-square Automatic Interaction Detector (CHAID), Exhaustive Chi-square Automatic Interaction Detector (ECHAID), Classification and Regression Tree (CRT), and Quick-Unbiased-Efficient Statistical Tree (QUEST). Six features were selected as the inputs of the decision trees including age, sex, annual income, educational level, occupation, and risk preference. Three hundred insurants from an insurance company in Taiwan were used as examples for establishing the decision models. Two experiments were conducted to evaluate the performance of the decision trees. The first one used the purchase records of primary insurances as examples. The second one used the purchase !
records of primary insurances and additional insurances. Each experiment contained four rounds according to different partitions of training sets and test sets. Discussion and concluding remarks are finally provided at the end of this paper.

Abstract: Partial discharges in a power transformer are often a predecessor of serious fault, as Power transformers are fundamental apparatuses in electrical power system network. Thus, partial discharge measurement are a significant diagnostic tool to supervise the insulation state of a power transformer, as elementry Partial Discharges (PD) detection is not adequate to make a decision about intervening, so the localization is required to evaluate the risk and to plan rectification actions. Acoustic signals collected by piezoelectric sensors established outside of the transformer, supply the accurate position of PD as parameters. Conclusion demonstrates the efficacious of suggested solution for PD source localization in oil insulating power transformers using Adaptive Tabu Search (ATS).

Abstract: Development of information society has been strongly supported by all governments including the government of the Czech Republic. Recently, ways how to evaluate efficiency of the investments and development of information society have been searched for. Paper deals with utilization of geographic information systems, spatial analyses and exploratory spatial data analyses (both global and local indicators) for evaluation of development of information society and participation of the citizens. Within the case study development in all 14 regions of the Czech Republic during last few years is evaluated. Evaluation is based on available data which were provided by Czech Statistical Office. One of the results is that Prague (the capital) was a leader in the first years but during last few years the other regions have made the gap on the capital smaller so many differences across the country have been decreased.

Abstract: The availability of terrestrial Free-Space Optical (FSO) link depends on the link margin, i.e. on the maximum atmospheric attenuation the link power budget can absorb. As the maximum output optical power of laser sources is limited by safety regulation the link margin can be increased by increasing the receiver sensitivity using avalanche photodiodes (APD). The diodes operate in a relatively narrow range of avalanche multiplication. The optimal reverse voltage depends on temperature and is subject to manufacturing variance. These effects are usually compensated for in the open-loop mode, where a DC source is programmed with average datasheet temperature coefficients and individually adjusted to compensate for manufacturing variance. The paper describes the design of a receiver with closed-loop stabilization of APD parameters.

Abstract: In this paper, we use feed forward neural networks with the back-propagation algorithm to build decision models for five insurances including life, annuity, health, accident, and investment-oriented insurances. Six features (variables) were selected for the inputs of the neural networks including age, sex, annual income, educational level, occupation, and risk preference. Three hundred insurants from an insurance company in Taiwan were used as examples for establishing the decision models. Six experiments were conducted in this study. These experiments were mainly categorized into two phases: Phase 1 (Experiments 1 to 3) and Phase 2 (Experiments 4 to 6). In Phase 1, we used the six features as the inputs of the neural networks. In Phase 2, we employed the factor analysis method to select three more important features from the six features. In Phase 1, Experiment 1 used a single neural network to classify the five insurances simultaneously while Experimental 2 utili!
zed five neural networks to classify them independently. Experiments 1 and 2 adopted the purchase records of primary and additional insurances as experimental data. Experiment 3, however, utilized the primary insurance purchase dada only. In Phase 2, we repeated the similar experimental procedure as Phase 1. We also applied statistical methods to test the differences of the classification results between Phases 1 and 2. Discussion and concluding remarks are finally provided at the end of this paper.

Abstract: Executing a program in parallel machines needs not only to find sufficient parallelism in a program, but it is also important that we minimize the synchronization and communication overheads in the parallelized program. This yields to improve the performance by reducing the time needed for executing the program. Parallelizing and partitioning of nested loops requires efficient iteration dependence analysis. Although many loop transformations techniques exist for nested loop partitioning, most of these transformation techniques perform poorly when parallelizing nested loops with non-uniform (irregular) dependences. In this paper the affine and unimodular transformations are applied to solve the problem of parallelism in nested loops with non-uniform dependence vectors. To solve these problem few researchers converted the non-uniform nested loops to uniform nested loops and then find the parallelism. We propose applying directly the two approaches affine and unimodul!
ar transformations to extract and improve the parallelism in nested loops with non-uniform dependences. The study shows that unimodular transformation is better than affine transformation when the dependences in nested loops exist only in one statement. While affine transformation is more effective when the nested loops have a sequence of statements and the dependence exists between these different statements.

Abstract: This paper treats the problems involved in the design of logic circuits based on novel processing platform. It begins with description of the ternary quantum-dot cell, an extended classic binary cell. These cells are basic building blocks of quantum-dot cellular automata. They are used to construct simple structures with inputs and output which implement some ternary logic function. These structures are employed as building blocks of larger and more complex circuits. The computer-aided design tool that finds an optimal implementation of a circuit by bottom-up approach is described. The search of a solution is based on iterative deepening. Since searching over all possible solutions is too computationally complex, heuristics are used to reduce the computation time.

Title of the Paper: Microstrip Patch Antenna for a Retinal Prosthesis and Rf Mems Technology

Number of paper pages: 10
Abstract: This paper is about the investigation of a novel approach for establishing a data telemetry link in a dual-unit retinal prosthesis at microwave frequencies (1.4GHz and 2.35GHz) using a pair of Microstrip patch antennas. Approximately sized extraocular (25 mm x 25 mm) and intraocular (6 mm x 6 mm) antennas are simulated using IE3D and compared with reference experimental results which was designed and fabricated using the Finite Difference Time Domain Method. Simulation results show frequency shift in the resonant frequency by changing the capacitor height from 2 ìm to 1 ìm. However, the major drawback of this configuration is as Microstrip antenna is loaded with radial stub, which makes the structure is not suitable for loading with large number of capacitors. Because the dimensions of the radial stub determine the separation between the MEMS capacitors. Hence, the overall dimensions of the structure grow as more MEMS capacitors are used for loading, which is a pro!
blematic issue in terms of fabrication.

Abstract: Wireless networks that employ adaptive antenna array (AAA) have been proposed to increase the traffic-carrying capacity and circuit quality. The AAA architecture generates a large number of areas since a cell is divided into several areas. Therefore, a high-mobility mobile host has a very high probability to cross the area boundary and needs to perform a handoff procedure in order to continue the current communication session. A handoff procedure including code switch, data switch, and even network switch will increase the system overhead. Each area has a set of system codes. When a call arrives at an area, if no codes are available in this area to serve this call, the call will be blocked. Accordingly, the number of codes allocated to an area will affect the communication quality in this area and the allocations of system codes among areas will affect the traffic-carrying capacity of a cellular system. A reasonable allocation should provide more codes to each area!
with heavy traffic than with light traffic. Otherwise, it will experience that the heavy traffic areas do not have sufficient codes to carry their traffic loads but the light traffic areas have many available codes. Thus, the traffic-carrying capacity of a system is reduced and the call blocking probability arises. To consider real-life networks, the traffic distributions among areas should be changeable according to various conditions. In order to achieve higher code utilization, when there are variations in traffic, the code allocations among areas should be effectively reallocated according to current traffic profile. The investigation proposes an effective load balance and handoff management strategy. These strategies are implemented to solve traffic-adaptation problem that can enhance the traffic-carrying capacity for variations in traffic. For the management of handoff procedure, our strategy considers the mobility of mobile hosts and the bandwidth utilization. It ca!
n decrease the number of handoff procedures and lessen the system over
head. Furthermore, the performance analysis and the simulation results are presented to confirm the efficiency of the proposed strategy.

Abstract: Switched Multiband Microstrip bandpass filters for IEEE 802.11a/b/g WLANs are presented. Cross coupled square open loop resonator type of filter is used as the basic design. These filters were selected since there was a tuning parameter available in the structure which changed the center frequency without change in performance. Two MEMS reconfigurable filter structures are proposed. Static simulations for each position of the MEMS switches were performed for S11 and S12 to observe the bandwidth and insertion loss of the filter. The simulations were performed on IE3D 10.06.

Title of the Paper: Investigation of Facial Artifacts on Face Biometrics using Eigenface based Single and Multiple Neural Networks
Authors as they appear in the Paper: K. Sundaraj
Email addresses of all the authors: kenneth@unimap.edu.my
Number of paper pages: 10
Abstract: Biometrics has been an important issue pertaining to security in the last few decades. Departments or agencies entrusted with national security are increasingly installing surveillance cameras in strategic or critical areas to monitor the identities of the general public. Upon locating suspicious characters in the video feed, they are compared with existing databases to find a match. These databases are generally compiled from the National Registration Department (NRD), Immigration, intelligence agencies, etc. Unfortunately, as mentioned in most reports of tragic events, suspicious characters do not resemble anything like what has been stored in the databases. There is a high chance that the face biometric identification software will miss these culprits. In this paper we propose to investigate the effects of facial artifacts on the recognition rate of eigenface based neural networks. It has been found that eigenfaces coupled with Euclidean distance can be successf!
ully used to recognize the human face in almost real-time. However, facial artifacts can cause the features that characterize a face to be distorted. Hence, it is desirable to identify problematic facial artifacts that can cause false identification or no identification. The main focus of this paper is the investigation of common facial artifacts on the performance of recognition and the proposition of modification to existing databases to improve the positive rate of identification. A professional graphic artist was used to modify the images used in the experiments. We use a single and multiple eigenface based neural network as the classifier in our experiments.

Title of the Paper: Homogeneous Pin-Through-Hole Component Inspection Using Fringe Tracking
Authors as they appear in the Paper: K. Sundaraj
Email addresses of all the authors: kenneth@unimap.edu.my
Number of paper pages: 11
Abstract: Automated visual inspection (AVI) systems are playing important roles in ensuring manufacturing quality in the electronic industry especially in the assemblage of printed circuit boards (PCB). Most existing AVIs that are used for PCB inspection are categorized as non-contact inspection systems consisting of a single overhead camera. Such systems, which can be manual or automated, are incapable of detecting 3D pin-through-hole (PTH) component placement defects and reporting them. By considering an assembled PCB as a textured surface with a predefined depth map, we propose to apply an angled fringe projection to detect defects in PTH component placement. It has been found that angled fringe projection can be used for surface analysis by applying phase shifting and phase unwrapping obtained from several images. However, the turnover time for PCB inspection is very crucial in the electronic industry. In other words, an alternative improved method that speeds up the ins!
pection process is always desirable. This paper describes a method of applying an angled fringe projection for 3D height measurement using a single captured image and a direct triangulation technique. The main focus of this paper has been made on the development of a fringe tracking algorithm and its practical implementation details. This algorithm allows us to obtain the depth map of the surface under analysis with just one image. The simulated data and calibration process of the tracking algorithm are discussed and an experimental result is given for Peripheral Component Interconnect (PCI) component insertion in computer motherboards. With proper system calibration and accurate image processing, we demonstrate the successful manipulation of a structured collimated light source for height measurement using a single captured image.

Abstract: This paper postulates the ascertainment of offline, optimal proportional-integral-derivative (PID) controller parameters of an automatic voltage regulator (AVR) system using Adaptive Tabu Search (ATS) algorithm. By minimizing the performance index such as integrated absolute error (IAE), the integral of squared error (ISE), and the integral time absolute error (ITAE) employed method, the parameters of this PID controller is acquired. For significant contrast, the classical tuning proposed by Ziegler and Nichols is applying compared with demostrated method. The performance of the proposed tuning mechanism had been demonstrated and analysed in efficient and robust in improving the step response of an AVR system with application to control of synchronous generator excitation system by selecting the suitable performance index.

Abstract: In hierarchical distributed control systems for hydro power groups located over a large area, there are requirements for independent (autonomous) operation of control systems for each power group (or parts of the group), to solve local problems or in case of real-time faults over communication paths with upper levels. In this case, the control equipment for power groups may be defined as holons, and their autonomy property ensures a decentralized relationship of heter-hierarchical type. There are presented the possibilities of the study of operational regimes of the plant using experiments performed on lab equipment. This is offering a methodology to implement alternate solutions for the control systems of power plants

Title of the Paper: The Effect of Frequency and Amplitude of Vibration on the Coefficient of Friction for Metals
Authors as they appear in the Paper: Jamil Abdo and Mahmoud Tahat
Email addresses of all the authors: jdabdo@squ.edu.om
Number of paper pages: 10
Abstract: Experiments were conducted to determine the effects of frequency and amplitude of vibration on friction. The experimental analysis also seeks to take into account a variety of factors influencing the coefficient of friction such as normal load and surface roughness. An in-house pin-on-disc apparatus was constructed with a spindle speed control and applied forced-feedback to perform the tests. The response surface methodology is utilized to investigate the effects of the factors and their cross influence on the coefficient of friction for the Steel C1020 and Aluminum 7079. The analysis of variance is done on the experimental data to evaluate the statistical significance of the model. The response equation for the coefficient of friction of Steel C1020 and Aluminum 7079 were determined. The ranges of frequency and amplitude of vibration were 120 – 600 Hz and 15 – 225 µm, respectively. Studies have shown that the coefficient of friction decreases with the incre!
ase of frequency and amplitude of vibration within the observed ranges for both metals whereas the in case of Aluminum 7079 the coefficient of friction is about 13 % when it compares with the coefficient of friction of Steel C1020.

Abstract: This paper applies the one and two parameter- item response models (IRT) with a probit link to derive a scale of financial precariousness. A strong focus is on the item testing and selection, which is sometimes ignored in the IRT literature. In order to test whether the items fulfil or not the IRT fundamental assumptions, a number of tests are applied. The Mokken Scale is the most comprehensive one and provides the most complex output. Also, the paper highlights the advantages of using the IRT instead of traditional models when deriving latent measures from a set of observable binary indicators. This is often the case in the economic and social fields where the IRT is rarely used. Using both IRT models and some testing procedures, we derive a scale of four items and estimate item parameters. In the empirical part, the IRT models are applied on data from the Luxembourg socioeconomic panel (PSELL-3, wave 2006) using the modules GLLAMM (for running the IRT models) an!
d msp/loevH (for testing the items) in the statistical package STATA. The software and modules allowing the application of the IRT models and its underlying tests are also examined. At the end, the paper leads to both empirical and methodological conclusions.

Abstract: This paper presents a 1x4 array antenna using asymmetric T-shaped slit loaded microstrip antenna (MSA). The antenna consists of four MSAs align vertically on a dielectric substrate and ground plane. This antenna will be utilized in WLAN applications as the commercial panel antenna. A modified array configuration is proposed to further enhance the antenna radiation characteristics and usable bandwidth. The desired patterns of array are improved by adjusting the array element spacing from lamda/2 down to lamda/3. Moreover, alternating of the slit loads positions on each side of some patches in array can control the directive patterns to be symmetric shapes. The measured results of the radiation pattern, input impedance, return loss, VSWR, directive gain, and are also conducted for verification of the IE3D-based simulated results. With good agreement between the simulated and measured results and accordance of the requirements, therefore, this proposed panel antenna i!
s appropriate for the wireless applications.

Abstract: Wind energy is a viable option to complement other types of pollution-free generation. In the past constant-speed wind turbine is used for the limitation of the control technology and manufacturing technology. But this kind wind turbine has low efficiency and small operation range. Recently, more and more people make their focus on studying the MW variable-speed wind turbine for its high efficiency in using wind energy and large operation range. In this paper, base on the study of the model for the variable-speed wind turbine, a multimode power control system is proposed. This control system is consisting of two controllers: the speed controller and the pitch controller. By judging the different power point, the control system use different controller to make the wind turbine run at different mode. Simulation results by using actual detailed parameters for wind turbine show the effectiveness and robustness of this control system.

Abstract: Term e-government is very broad and covers all activities leading to better communication among public administration offices and third parties (citizens, business and government itself). The main goal is to transform service delivery from personal to online. However, these e-government innovations are often delayed by legal, organizational and other obstacles. The first part of this paper is focused on a legislative support for a transfer of chosen services (agendas) of a community to e-form. The second part is about analysis and mapping of the process flow of these services. After that, evaluation and the description of problems which are connected with this transfer follow, according to project held the Municipal authorities in Jièín.

Abstract: Substation Automation Systems (SAS) are widely used for the purpose of control, protection, monitoring, communication etc. in substations to improve the reliability of the power supply. SASs adopting IT based solutions such as Ethernet LAN have recently become more common although hardwired control has been used in the past in earlier versions of SAS utilising simple communication methods. Moreover, IEC 61850 which is the international standard for communications within substations has been published, and the application of SAS based on IEC 61850 is increasing. It is necessary to select each component and the configuration of the SAS from the viewpoint of dependability so that the dependability of the SAS, i.e. reliability, availability, and serviceability may have a very big impact in the stability of the power supply in the electric power transmission and distribution systems. In this paper, we will describe the configuration policy of an IEC 61850 based SAS, its!
actual system configuration and the redundant configuration to improve dependability. In addition, we will explain some of the new functions not currently covered by IEC 61850 that we have developed to improve usability and availability. Following which we will present an evaluation of the dependability for MTTF (Mean Time To Failure), Availability, and FMEA (Failure Mode and Effects Analysis) for these configurations of SAS based on the dependability requirements for SAS. Furthermore, other measures have been adopted in the design to ensure fail-safe and fool-proof operation and thus improve system dependability in a much wider sense

Abstract: Energy consumption strategy is crucial to the future of Broadband Wireless Access (BWA). In order to manage limited battery power efficiently, the IEEE 802.16e standard defines the sleep mode operation in its MAC protocol to maximize the lifetime of Mobile Station (MS) and to enhance the network capability. In this paper, we analytically investigate the power consumption of listening state and sleep state operations of IEEE 802.16e. A Mobile Station goes to sleep mode when there is no data to send or receive with the Base station (BS). After a Mobile Station stays in sleep state for a pre-defined time, it wakes up and transits to listening state periodically to check if the Base Station has any buffered downlink traffic destined to the Mobile Station itself. Although the listening interval is shorter than sleep interval, the power consumption should consider both listening state and sleep state operations. Our proposed model and numerical results prove the listenin!
g state may consume up to 90% of the total power consumption in some case.

Abstract: In this paper we survey several aspects related to normal forms of hyperedge replacement grammars. Considering context free hyperedge replacement grammars we introduce, inspired by string grammars, Chomsky Normal Form and Greibach Normal Form. The algorithm of conversion is quite the same with the algorithm for string grammars. The important difference is related to the fact that hyperedge grammars are two-dimensional and that's why parsing productions, in order to transform into string grammars, can be done only nondeterministic. A detailed example of conversion to both normal forms is introduced to clarify all the algorithm steps

Abstract: The paper presents the implementation of a 3D acquisition system intended to be used as a tool in the conservation of folk heritage objects. We developed a computational efficient and cost effective 3D reconstruction system used for acquiring, reconstructing and presenting the 3D shape of heritage objects. The proposed solution for 3D reconstruction is based on a phase shifting fringe projection algorithm. This paper presents a simple analysis of fringe pattern reconstruction models as well as the details of our solution. The result proves that the proposed method is suited for such applications and is more widely applicable.

Abstract: This paper includes the study of a very simple reference current source, with cross-connected known current mirrors, where the thermal-compensation of the sum of branch currents (the total current) is done. This kind of approach is adequate when the reference must supply current in a charge with grounded or connected to voltage supply end. The first and second-order thermal compensation of the reference current are analyzed and the equations representing the total current compensation conditions are established. The current reference is designed in a CMOS 0.35µm process and his quality has been verified by simulation. The simulation results show the possibility of achieving good performances for a total current of 8...15µA, across a temperature range of 0 - 100oC: for only first-order thermal compensation, an average thermal drift of -200 ppm/ oC (or a maximum variation < 2%) and for second-order thermal compensation – a maximum variation < 0.45%.

Abstract: Grammatical Inference deals with the problem of learning structural models, such as grammars, from different sort of data patterns, such as artificial languages, natural languages, biosequences, speech and so on. This article describes a new grammatical inference tool, Grammar-based Classifier System (GCS) dedicated to learn grammar from data. GCS is a new model of Learning Classifier Systems in which the population of classifiers has a form of a context-free grammar rule set in a Chomsky Normal Form. GCS has been proposed to address both regular language induction and the natural language grammar induction as well as learning formal grammar for DNA sequence. In all cases near-optimal solutions or better than reported in the literature were obtained.

Abstract: At the present, many universities do not have enough teaching staffs for programming training. The teacher cannot give suggestions in a timely fashion to all of the students who need guidance for their programming problems. The training condition reduces motivation to learn programming of the students. We propose a model to promote collaborative learning among the students. In the model, the students are combined into small groups to practice programming. Although every group member has to do programming independently, they are encouraged to share programming problems with other group members to find out solution. The voting mechanism is applied to each group. If a group member gives an opinion which is evaluated convincing one, the member is rewarded by others with COOP points. For effective collaboration of students in each group, we combine students based on two features of each student. One is programming ability, which are scores of the source codes. The other!
is contribution to group, which are COOP points accumulated during the collaborative learning. Using the model, we developed a collaborative learning environment, Col-E. The Col-E has been applied to actual classes in Ritsumeikan university, Japan. The experiment results show that Col-E has good possibilities to improve any kinds of students.

Abstract: This paper describes an interval type-2 fuzzy modeling framework, reduced-set vector-based interval type-2 fuzzy neural network (RV-based IT2FNN), to characterize the representation in fuzzy logic inference procedure. The model proposed introduces the concept of interval kernel to interval type-2 fuzzy membership, and provides an architecure to extract reduced-set vectors for generating interval type-2 fuzzy rules. Thus, the overall RV-based IT2FNN can be represented as series expansion of interval kernel, and it does not have to determine the number of rules in advance. By using a hybrid learning mechanism, the proposed RV-based IT2FNN can construct an input-ouput mapping from the training data in the form of fuzzy rules. At last, simulation results show that the RV-based IT2FNN obtained possesses nice generalization and transparency.

Abstract: Field programmable gate arrays (FPGAs) have been used in a wide range of applications including the field of telecommunications. This paper presents the use of FPGAs in the implementation of both analog and digital modulation that includes amplitude modulation, frequency modulation, phase modulation, pulse code modulation, pulse width modulation, pulse position modulation, pulse amplitude modulation, delta modulation, amplitude shift keying, frequency shift keying, phase shift keying, time division multiplexing and different encoding techniques like non-return-to-zero line code, non-return-to-zero mark line code, non-return to zero inversion line code, Unipolar return-to-zero line code, bipolar return-to-zero line code, alternate mark inversion line code, and Manchester line code. Moreover, an FPGA can be designed to emulate a particular device like an oscilloscope, a function generator, or the like. This paper describes the capability of an FPGA to internally gene!
rate a low frequency input signal and through the use of a VGA port, it is able to display the signals in an output device. However, the use of FPGAs is not limited to the aforementioned applications because of its reconfigurability and reprogrammability.

Abstract: Up to now, an optically differential reconfigurable gate array taking a differential reconfiguration strategy and a dynamic optically reconfigurable gate array taking a photodiode memory architecture have been proposed. The differential reconfiguration strategy provides a higher reconfiguration frequency, with no increase in laser power, than other optically reconfigurable gate arrays, however the differential reconfiguration strategy can not achieve a high-gate-count VLSI because of the area occupied by the static configuration memory. On the other hand, the photodiode memory architecture can achieve a high-gate-count VLSI, but its configuration is slower than that of the optically differential reconfigurable gate array using equivalent laser power. So, this paper presents a novel inversion/non-inversion dynamic optically reconfigurable gate array VLSI that combines both architectures. It thereby achieves both advantages of rapid configuration and a high gate coun!
t. The experiments undertaken in this study clarify the effectiveness of the inversion/non-inversion optical configuration method.

Abstract: The term power quality is, in general, closely related to the quality of the voltage. Considering the widespread presence of sensitive loads in the electric grid, and the increasing awareness of the consumers concerning the quality of the power supply, the control and measurement of power quality parameters, for instance, harmonics, interharmonics, sags, swells, etc., are increasingly becoming much more important [1, 2, 3, 4]. Most of the necessary calibration procedures for power quality monitors and power quality analyzers are already defined in the international standards, mainly in the IEC 61000 series [5] and ANSI/IEEE Standards. This paper presents results of a research intended to develop a methodology for the calibration of high voltage transducers for power quality measurements in high voltage networks, considering that such kind of procedures are not yet established in the pertinent standards. In this research it is also considered that the conventional h!
igh voltage laboratory is not suitable for power quality tests, so some improvements are necessary on this subject. In this development, modelling and computer simulation using ATP – Alternative Transients Program [6] were used for to assess the frequency response of the test setup, and the design of the reactive compensation of the test circuit.

Abstract: - In this paper we describe the neural fuzzy filtering properties in real-time sense; giving an approach about the real-time neuro-fuzzy digital filters, defined in acronym form as RTNFDF. This kind of filters require the adaptive inference mechanism into the fuzzy logic structure to deduce the filter answers in order to select the best parameter values into the knowledge base (KB), actualizing the filter weights to give a good enough answers in natural linguistic sense; this require that all of the states bound into RTNFDF time limit as a real-time system, considering the Nyquist criteria. In this paper we characterize the membership functions into the knowledge base in a probabilistic way respect to the rules set decisions without lost its real-time description, performing the RTFNDF. Moreover, the paper describes in schematic sense the neurons set architecture into the filter description. The results expressed in formal sense use the concepts exposed in the pap!
ers included into the references. Finally, we present in illustrative manner the RTNFDF operations using as a tool the Matlab© software. Explicitly, the paper has eight sections conformed as follows: 1. Introduction, 2. Neural Architecture, 3. Rule Base Dynamics, 4. Neural Rules, 5. Real-time Descriptions, 6. Restrictions for RTNFDF, 7. Simulation, Conclusions and References.

Abstract: Planners and designers are interested in projects that express spatial ideas and have meaning for the general population. The design of peace gardens and peace parks is one type of place where designers have opportunities to express ideas and connect with the public. We examined two peace related environments: the Dalian World Peace Park in China and the International Peace Garden on the border between the United States of America and Canada. Both parks attempt to symbolize peace in a conceptual manner. Both parks are located on sites of historical significance. Because of their somewhat remote locations, they can both suffer visitation problems. However their remote location also makes both parks unique and not as crowded as other parks. The peace park movement is growing as numerous other peace parks are being planned around the world.

Abstract: The Mobile IP network environment for users is very vulnerable to malicious attacks, such as denial-of-service, man-in-the-middle, and other types of attacks. For protection, the IETF standard Mobile IP protocol is modified with IP security (IPSec) primitives, which control the packet flow from a mobile host through multiple security gateways. In addition, IPSec uses strong cryptographic authentication and encryption algorithms to protect the integrity and confidentiality of IP traffic. In this paper, we proposed a key management algorithm for Mobile IP networks based on IPSec. The proposed scheme includes two parts: a wired network and a wireless network. In the wired network part, the proposed scheme produce two keys in each security gateway, transfers a packet with an encrypted key and receives a packet with a decrypted key. In the wireless network part, we use AH to arrive at wireless segment packet security. By the proposed scheme, we can enhance the security !
of Mobile IP networks.

Abstract: Paper discusses new economic districts and spatial structures of the economic activities in metropolitan areas influenced by transitional processes and globalisation. It indicates the impacts of new economic trends and economic districts on creation of metropolitan areas' spatial organisation. Paper shows mechanisms of the agglomeration of new economic poles and spatial-economic clusters in metropolitan areas. These mechanisms have consequences on economic and spatial changes, on changes of urban, regional and social structures, on environmental degradation, etc. New economic zones in metropolitan areas are result of market pressures, the increase of economic competitiveness and influences of foreign and domestic companies on the territorial capital of those areas and their urban/ spatial structures. There are indications of possible development impacts on creation of new economic districts with the preliminary analyses of Belgrade metropolitan area. Paper conclude!
s that new economic districts – new industrial, commercial, entrepreneurial zones that developed systematically or spontaneously in the suburban areas (along highways) of Belgrade metropolitan area, have a major role in spatial development of economic activities and in the planning of territorial organization of this area.

Abstract: Current growth in the tourism industry especially in the South East Asia region has sparked the emergence of various resort amenities to cater for the tourists' needs. In vying for the influx of tourists, tourism spots and destinations such as Bali, Phuket and Langkawi and other resort locations in the region, strive to offer tourists a more culturally sensitive form of travel accommodation. These infamous tourism and resort destinations has distinctively portrayed the exquisiteness of the traditional regional architecture as its prime development concept and resort identity. This uniqueness interpreted an authentic aesthetical values and strong ethnic cultural influence which is often translated into a concept known as 'authentic regionalism'. The exquisiteness of the traditional Malay architecture, known as Malay vernacular architecture, symbolizes decades of richness of the Malays' cultural heritage, creativities and civilization. Traditional Malay designs inter!
preted strong aesthetical values and cultural influence, which are relatively patterned from the Malays' creative attitudes together with their sensitivities and intimate relationships with their surroundings. In other words, the industry strive to offer an environment as 'local' as possible without sacrificing creature comforts. This paper will cover element of regionalism, approach, issue and character in the tourism Architecture in Malaysia. It will also presents the analyses primarily in regards of construction materials adapted in the development of resorts in Malaysia as the fundamentals for sustainable development and how successful the adaptation is in representing the Malay vernacular architecture

Abstract: In order to improve the power quality maintenance and reliability of power supply, different types of faults on the transmission line namely: open-circuit (OC), short-circuit (SC), high impedance faults (HIF) and the fault caused by direct lightning strike (LS) have been investigated in this paper. The disturbances have been modelled and simulated using a well-known transient simulation tool - Alternative Transient Program/ Electromagnetic Transient Program (ATP/EMTP) and the resulting data are then imported into MATLAB for the investigation on the traveling wave (TW) reflection pattern and harmonic behaviour . Study on the characteristics of the faults in terms of their corresponding frequency spectrum, the polarities of the incident-wave and reflected-wave has been performed and the possibility to differentiate the type of fault is explored. For this purpose, the fault on the wave has been created at the moment when the voltage signal reaches its peak and also wh!
en it is close to zero. Both, Wavelet Transform (WT) and Fast Fourier Transform (FFT) methods have been used to analyze the transient signals generated by the fault. Model of the network used in this study is taken from [1]-[2].

Abstract: Wind energy is a viable option to complement other types of pollution-free generation. In the past constant-speed wind turbine is used for the limitation of the control technology and manufacturing technology. But this kind wind turbine has low efficiency and small operation range. Recently, more and more people make their focus on studying the MW variable-speed wind turbine for its high efficiency in using wind energy and large operation range. In this paper, base on the study of the model for the variable-speed wind turbine, a multimode power control system is proposed. This control system is consisting of two controllers: the speed controller and the pitch controller. By judging the different power point, the control system use different controller to make the wind turbine run at different mode. Simulation results by using actual detailed parameters for wind turbine show the effectiveness and robustness of this control system.

Abstract: Wireless market, such as cellular systems and wireless LAN, becomes huge and is still expanding. Since operational frequency and transmission bit rate are increasing, much more base stations or access points are necessary to overcome capacity and link budget problems. Most of the places suitable for the base station were already occupied by the existing systems. In the future, sometimes, new base station must be installed at the places where power supply or transmission cable is not available. The proposed repeater system is applicable for such case. The RF signals are fed to the repeater through the air by optical beams. And electrical power is fed by the optical beam, too. This paper describes the design principle and experimental results of the proposed system. For example, by using 26cm diameter optical beam for power transmission, available forward link RF power at the repeater station is 10mW in the case that the distance between the base station and the repe!
ater station is 40 m. If a diameter of the optical beam for power transmission is 48 cm, 100 mW RF output power is available for a forward link. Since micro cell structure will become majority in the future high frequency and high bit rate cellular and wireless LAN systems, these amount of RF output power may be enough for many cases.

Abstract: Numerical modeling is nowadays an essential tool for all researchers involved with the field of electrical, mechanical engineering, physics and etc. The object of this paper is to provide a clear, easy and understandable study on FEM (finite element method) using MATLAB and MATHEMATICA, which both provide powerful support to solve large equations. 1D and 2D FEM solutions are studied on electromagnetic (EM) field distribution which is one of the essential parts of electrical engineering. The results from the two different programs were compared with those obtained by using the finite difference method (FD). Computer programs and formulations of the finite element technique have been constructed to make the concept more understandable and explicit for engineering students and practicing engineers.

Abstract: The procedure for analysis of electromagnetic field in a cylindrical metallic cavity, based on reflection and transmission characteristic, is presented in the paper. An analysis of procedure efficiency to resonant modes identification is conducted numerically and experimentally verified. As a numerical tool, TLM time-domain method, enhanced with the compact wire model to account for the presence of feed and monitoring probes, is used. Conditions, in terms of probe dimension, for achieving the best source matching and optimum coupling between ports, are considered. Results obtained using reflection and transmission procedures are also compared, in terms of modes identification and resonant frequency dependence of probe dimensions.

Abstract: Nowadays, the industrial processes are controlled mainly by using Programmable Logic Controllers (PLC). Anyway, the more strict specifications imposed at present day are bringing about the gradual introduction of advanced control techniques (fuzzy, adaptive, …) in industry. In order to soundly implement such techniques, new hardware (DSP, Industrial PC, …) may be necessary. This paper describes a complete environment for a realistic experimentation on advanced controllers in order to facilitate its study and posterior implementation in productive processes. The experimentation environment is formed by an industrial PC that acts as real time controller and other PC or real actuators like process plants. Hardware-in-the-loop (HIL) experimentation provides a very useful tool for testing systems or subsystems at early stages of the development process. This can reduce the debugging process of the system, in addition to eliminate project risks, because hardware prototyp!
e is not necessary before carrying out testing and system integration. HIL experimentations work in real time and carry out input and output operations as a part of the real system in their operative environment. This enables the system or subsystem to be tested under work nominal conditions as well as at its intended operational boundaries.

Abstract: In Past decade, Thailand has regularly faced the problem of flash flood and landslides, especially over the lower Northern part of the country. This area is mountainous area where there is the problem of raingage scarcity and absence. In order to construct the effective warning system, the appropriate rainfall estimation should be first developed. Thus, this research was implemented based on the concept of using information from radar to detect rainfall in order to solve the problem of information lacking over ungaged area. This research was setup under the collaboration among Naresuan University, Thai Meteorological Department and Royal Irrigation Department. The objective of the research is to estimate the rainfall (R) from Z-R relationship by using the measured reflectivity (Z) from radar station located at the middle of flash flood risky area in Lower Northern Thailand. Coupling GIS technique with probability matching, the Spatial Probability Technique (SPT) a!
nd Buffer Probability Technique (BPT) were developed to evaluate the appropriate Z-R pair for Z-R relationship analysis. From both techniques, the obtained Z-R relationship can be expressed in form of , where are Function Parameters, as the previous studies. Comparing between these two techniques on rainfall detecting from reflectivity, the obtained R2 from both processes are slightly difference, whereas, BPT provided less standard error of estimation. However, this study emphasized only on the Z-R relationship, the further study should be done with the other parameters to support the disaster warning system in the future.

Abstract: This paper is focused on acoustic modeling for spontaneous speech recognition. This topic is still a very challenging task for speech technology research community. The attributes of spontaneous speech can heavily degrade speech recognizer's accuracy and performance. Filled pauses and onomatopoeias present one of such important attributes of spontaneous speech, which can give considerably worse accuracy. Although filled pauses don't carry any semantic information, they are still very important from the modeling perspective. A novel acoustic modeling approach is proposed in this paper, where the filled pauses are modeled using the phonetic broad classes, which corresponds with their acoustic-phonetic properties. The phonetic broad classes are language dependent, and can be defined by an expert or in a data-driven way. The new filled pauses modeling approach is compared with three other implicit filled pauses modeling methods. All experiments were carried out using a!
context-dependent Hidden Markov Models based speech recognition system. For training and evaluation, the Slovenian BNSI Broadcast News speech and text database was applied. The database contains manually transcribed recordings of TV news shows. The evaluation of the proposed acoustic modeling approach was done on a set of spontaneous speech. The overall best filled pauses acoustic modeling approach improved the speech recognizer's word accuracy for 5.70% relatively in comparison to the baseline system, without influencing the recognition time.

Abstract: The Quantitative seismocardiography (Q-SCG) opens a new field of cardiovascular dynamics examination. Using this absolutely non-invasive method, a new field of monitoring heart rate variability was opened up. Systolic forces as well as heart rate variability in relation to changes in external stimuli are registered. Q-SCG probably offers a more complex view of both inotropic and chronotropic heart functions. It will be suitable for: examining operators exposed to stress; for assessing the effect of work, fatigue and mental stress; for monitoring persons as part of disease prevention; for determining a person's ability to carry out their duties both on the ground and in the air. Also heart rate variability can be measured. An electronic system for acquisition of data for noninvasive Q-SCG and signal processing is also presented. The measuring system is based on 16-bit sigma-delta analog/digital converter, microcontroller and personal computer. A special digital smo!
othing polynomial filter is used for signal processing. The example of real measured and evaluated signal is also shown.

Abstract: Abstract: High blood pressure is a major risk for cardiovascular disease. Blood pressure is determined by the underlying hemodynamics. An inexpensive system capable of noninvasive determination of blood pressure and hemodynamics could help to improve diagnosis and treatment of high blood pressure. A system (Carditor) for noninvasive determination of blood pressures and hemodynamics is presented. The system consists of a wrist cuff, a battery powered module with pneumatic and electronic circuits, and a notebook computer. The computer controls cuff inflation, deflation and data acquisition functions during gradual cuff deflation. Proprietary software is used to analyze oscillometric waveforms obtained from the radial artery. Systolic, mean and diastolic blood pressures and stroke volume are computed first. Stroke volume is then adjusted for body area and the adjusted value is used to compute cardiac output. Total peripheral resistance and systemic arterial complianc!
e are computed from arterial pressures, cardiac output and stroke volume. The computed hemodynamic variables are displayed on the computer screen in a "quadrant" graphic form. Preliminary hemodynamic data from from a group of 41 men and women (age 17-76) were used for qualitative comparison with published data (deSimone, n=544). Carditor results: stroke volume=76 ml, heart rate=70 bpm, cardiac output=5.3 l/min. DeSimone results: stroke volume=81 ml, heart rate=68 bpm, cardiac output=5.5 l/min. Examples of test results and clinical applications of the system are discussed.

Abstract: A multi-objective wireless local area network (WLAN) design models have been developed to optimize the network quality of services. The proposed model combines three problems together, including the optimal access point placement, the frequency channel assignment and the power level assignment. In addition, it accounts for user population density in the service area, traffic demand characteristics and the physical structure of the service area. The design model aims to determine a network configuration that optimizes the network quality of services in term of the radio signal coverage and the data rate capacity to serve expected user traffic demand in the service area. Numerical results and sensitivity analysis is performed to analyze the improvement of the network performance. We found that when we incorporate the issue of the user data rate capacity in the design model, we can greatly improve the quality of service in term of data rate requirement while slightly !
degrading the signal coverage availability. It is observed that as the weight factor of the user data rate capacity objective increases from 0 to 1, the user satisfaction level increases about 40% while the signal coverage availability decreases about 10%.

Abstract: In this paper, a novel spatial domain 2-D sigma-delta modulation using two-layered discrete-time cellular neural networks (DT-CNNs) with multi-stage noise shaping (MASH) property is proposed. Although the sigmadelta modulation is widely used for realizing of analog to digital converter (ADC), sigma-delta concepts are only for 1-D signals. Signal processing in the digital domain is extremely useful in 2-D signals such as image processing, medical imaging, ultrasound imaging and so on. In the proposed architecture, the A-template is used for a digital to analog converter (DAC), the C-template works as an integrator, and the nonlinear output function is used for the bilevel output. Besides, due to the CNN characteristic, each pixel of an image corresponds to the cell of CNN, and each cell is connected spatially by the A-template. Also, the multi stage noise shaping (MUSH) property, which is one of a very effective framework for a high order sigma-delta modulation, is !
exploited for realizing a second order sigma-delta modulator by cascade connected first-order CNN sigma-delta modulators.

Abstract: In clustering-based wireless sensor networks (WSNs), a certain sensing area is divided into many sub-areas. Cluster formation and cluster head selection are well done in the setup phase. With the pre-determined probability and random, every round in the WSNs has the different cluster numbers and cluster heads. However, the well known technique in cluster-based WSN is especially the low energy adaptive cluster hierarchy (LEACH) and its energy performance is improved due to the scheme of clustering, probability, and random. The clustering-based WSN has sensor nodes organized themselves with the pre-determined variable p to form clusters. With the pre-determined p variable and probability, every round has different cluster numbers which are not the optimal solution. Therefore, in order to evenly consume nodes¡¦ energy, this paper proposes a fixed optimal cluster (FOC) numbers that is to analyze the entire network first to have the optimal cluster numbers and then app!
ly it to form the optimal cluster numbers. Moreover, there are two different types of the optimal cluster numbers depending on the location of the base station. One is that the base station is setup at the center of the sensing area. The other is that the base station is setup at the far way of the sensing area. Finally, by the optimization analysis of cluster numbers applied to the ad-hoc WSN before sensor nodes are randomly deployed, the simulation results show the entire network lifetime can be extended very well.

Abstract: A wireless sensor network contains many sensor nodes in a certain sensing area. Every sensor node consists of a central processing unit, transmitting unit, receiving unit and power supply unit. In order to have efficient sensed messages, both the base station and sensor nodes have to communicate for each others as well. Therefore, a certain sensing area is divided into many sub-areas and every sensor node transmits its message to cluster head which, normally, will integrate and forward these messages to the base station. At the first step, set-up phase is applied to form clusters and to select cluster heads. During the second phase, the transmission phase, every sensor node received a message from another node has to transmit a confirmed message, acknowledgement (ACK), to ensure whether or not the data has been received which means every sensor node will dissipate much energy on transmitting and receiving. However, this paper proposes an adaptive routing protocol c!
alled Non_Ack in the Ad-hoc wireless sensor networks that is the data for every sensor node is transmitted directly to the cluster head and then forwards back to the base station. Some conditions for these sensor nodes with the sensed data directly transmitted without any acknowledgement may be failed so that this paper also considers as nodes fail to transmit the data back, the base station will be taken over for the network. By the consideration of these failure nodes, the base station will establish a binary tree for fault tolerance. A binary tree in the base station is also a big help for query-based routing protocol. Finally, simulation results reveal the entire network lifetime can be extended well and the performance is much better.

Abstract: The paper discusses several effects influencing the propagation in a laboratory wireless test bed, and also aspects important for designing and setting up the wireless test bed with space constraints. A numerical electromagnetic model for the full scale 7×7 wireless mesh network test-bed is discussed. The model includes the coupling and diffraction effects, and is based on the method of moments. The results of numerical simulations are validated with microwave, antenna and received signal strength (RSSI) measurements. The methodology developed for the Wi-Fi card based measurements and relying on the RSSI values is also discussed. The findings from the simulations help to quantify errors and provide grounds for suggestions towards improving design of test-beds.

Abstract: In this paper, a behavioral framework is proposed to solve dynamic GNSS positioning problems, which in the mean time may also provide a way to determine the DOP (dilution of precision) of a moving object. The concept of behavioral framework was first proposed by Jan C. Willems in a series of papers (J.C. Willems, "From time series to linear system - part I, II, and III," Automatica Vol. 22, 1986.) as a generic tool for mathematical modeling of dynamical systems. In the proposed approach, a GNSS positioning problem is firstly described by a kernel representation and then the problem can be solved by a structured total least-squares (STLS) algorithm. STLS algorithm is a modified version of the traditional total least-squares (TLS) method. It can be shown that the STLS algorithm is able to provide better performance than the TLS algorithm for the problems that possess a particular structure. In the case of the present paper, it is shown that the GNSS positioning probl!
em has a Hankel structure (i.e., the geometric matrix of the pseudorange equation is Hankel), therefore the problem can be solved by an STLS algorithm subject to a Hankel structure. On the other hand, a formula for calculating DOP of a dynamic positioning problem is also provided. The proposed method is able to calculate the DOP value for multiple time epochs, in compared with the conventional DOP formula which can only be derived at a single time epoch, so as to reflect the inter-dependency between consecutive time epochs.

Abstract: Abstract: -The paper presents a perception oriented linguistic formal model for 3D sensors depth images. Both the static object extraction and short term dynamic evolution in the scene are analyzed. The target applications are subsystems in action involved in independent environment exploration and learning be it human or machine. Field of view depth images obtained with recently developed CMOS 3D sensors are analyzed in their capacity to provide immediate action oriented data. For the 3D scene images a selective segmented method is proposed in terms of salient objects in the depth image. The model as proposed uses a representation of the scene depth image in terms of object area and mean center location. An original abstract formal language representation is proposed. The extension of the context free grammar with attributes ads structure to the model. It is also shown that the generated language translates directly depth labeling into action planning on the !
environment. The performance of the proposed abstract representation method is analyzed in terms of estimated computation time and direct semantic relevance for a sample application. For applications of object motion detection and tracking the formal model was extended with attributes for direction and speed. The object position drift based on segment correspondence for speed determination is shown to be compatible to the formal model as proposed. Further development of the model for multi layered representations for more complex applications areas is also outlined.

Abstract: Strength, Weakness, Opportunity and Threat (SWOT) analysis is an established methodology for assisting the formulation of strategy. This paper proposes a new quantified SWOT analytic method incorporated with the vote-ranking method. The indices of SWOT are voted, weighted and quantified to assess the competitive strategy, from top to the bottom, meanwhile the total weighted scores method will be used to get the best strategy alternatives. The competitive strategies of the Taiwanese Small and Medium Enterprises (SMEs) in the Environmental Management Systems (EMS) are taken as a case study, where eighteen certificated ISO9000 or ISO14000 auditors (or lead auditors) are invited to establish a decision group. Under the impact of environmental factors, the results show that company¡¦s image and profitability is the most important strategy for SMEs within the global markets. Lastly, Taiwanese SMEs apperceive the significance of EMS and also recognize the importance to su!
rvive within the diversified competing market environment, whereas they need to build up its environmental management that has to suit the EMS specification and attention. The findings are also applicable for other developing countries within the global markets or barriers.

Abstract: In this paper, first we describe the deficit scaling algorithm for minimum flow in bipartite networks. This algorithm is obtained from the deficit scaling algorithm for minimum flow in regular networks developed by Ciupalã in [5] by replacing a pull from a node with sufficiently large deficit with two consecutive pulls. This replacement ensures that only nodes in N1 can have deficits. Consequently, the running time of the deficit scaling algorithm for minimum flow is reduced from O(nm+n2 logC) to O(n1m+n12 logC) when it is applied on bipartite networks. In the last part of this paper, we develop a parallel implementation of the deficit scaling algorithm for minimum flow in bipartite networks on an EREW PRAM. The parallel bipartite deficit scaling algorithm performs a pull from an active node with a sufficiently large deficit and with the smallest distance label from N1 at a time followed by a set of pulls from several nodes in N2 in parallel. It runs in O(n12 log !
C log p) time on an EREW PRAM with p = &#61673;m/n1&#61689; processors, which is within a logarithmic factor of the running time of the sequential bipartite deficit scaling algorithm for minimum flow.

Abstract: Deregulation policy has caused some changes in the concepts of power systems reliability assessment and enhancement. In this paper, generation reliability is considered, and a method for its assessment using intelligent systems is proposed. Also, because of power market and generators’ forced outages stochastic behavior, Monte Carlo Simulation is used for reliability evaluation. Generation reliability, merely focuses on interaction between generation complex and load. Therefore, in this research, based on market type and its concentration, reserve margin, and various future times, a Neuro-Fuzzy system is proposed for evaluation of generation reliability which is valid and usable for all kinds of power pool markets. Finally, the proposed method is assessed on IEEE-Reliability Test System with satisfactory results. It will be shown that if market becomes more concentrated or price elasticity of demand increases, reliability will improve.

Abstract: The rapid development of E-Commerce not only generate huge amount of business opportunities but also raises a new question to the supporting platform of E-Commerce. Nowadays, E-commerce platform design is one of the hot spot of E-commerce research. The traditional 3-layered E-commerce platform can¡¯t meet the requirement of today¡¯s E-commerce application which is more complicated than before. The most significant disadvantage of today¡¯s platform is that it can not let clients share the commercial data in terms of their need and the platform is not in a form of a whole assembled software or webpage package reflecting various kinds of need of the customer or providing solutions for each specific customer request. The paper firstly use the use case diagram to analyze requirement of the third party E-commerce platform and then give a SOA based solution called IFTPEC in which information integration ability is assembled. Then the paper analyzes its architecture and su!
pporting environment and discussed its information fusion model. The implementation of the system can resolve these two questions and provides effective support for integration and operation for the complicated and dynamic E-commerce mode.

Abstract: Inevitabl in the practical supply chain planning, uncertainties, including unsure demand and various risks such as machine failure and transportation loss, are fundamental issues for all members of the supply chain. In this research, a mathematic model of supply chain with risk and uncertain demand are established and solved. The inherent complexity of such an integer programming model leads to the solving difficulty in speedily finding exact and integer optimal solutions. Therefore, a quick and decent answer becomes essential to pace up with the competitive business world, even it is usually only an approximate estimate. Four types of model are discussed in this study, including certain demand without risk, certain demand with risk, uncertain demand without risk, and uncertain demand with risk. After model verification and validation, computer simulations are performed with three selecting policies, namely ¡§low cost first¡¨, ¡§random¡¨, and ¡§minimum cost path¡¨.!
The results are analyzed and compared, in which the ¡§minimum cost path¡¨ is the better policy for node selection according to simulation runs. A general linear programming solver called LINDO was used to find the optimal solutions but took days as the problem size increases, while simulation model obtains an acceptable solution in minutes. For small size problems, numerical examples show that the Mean Absolute Percentage Error (MAPE) between integer simulation solution and mathematical non-integer solution falls into the range of 3.69% to 7.34%, which demonstrates the feasibility and advantage of using simulation for supply chain planning.

Abstract: Among the energy expenses for a building, the lighting system can contribute up to 50% of the total electrical consumption, and especially large quantities of energy are used in schools and office buildings. One possible method to reduce such consumption is to exploit solar, or natural, light. Through natural light, it is possible to illuminate indoor environments while maintaining appropriate illuminance levels necessary for indoor activities. Indeed, it is a mistake to search for the maximum energy savings, if this creates a possible disturbance to a person's visual health in the office. Moreover, it is important to highlight that the light quantity is not enough to evaluate the working comfort; the light quality must also be held in consideration. Therefore, for optimal energy savings, the most favorable combination of the elimination of energy waste, the light quality, and the light quantity must be assessed.

Abstract: The impact of voltage source and initial conditions on the initiation of ferroresonance is investigated. The investigation is carried out by simulating the behaviour of the mathematical model of ferroresonant circuit realized in the laboratory. The initiation of ferroresonance is investigated by varying the values of phase shift and amplitude of voltage source in order to incite the ferroresonance. Thereby, the initial conditions are varied within a practically possible range of initial values of transformer voltage and transformer flux linkage.

Abstract: There are several Initial Public Offerings (IPOs) regulatory changes implemented in Taiwan stock markets since 2005. One of those new mechanisms is to release the stock IPOs pricing rules to underwriters. The underwriters and listed companies have been growing up rapidly in recent years, and the whole offer size has become full-scaled. However, foreign scholars found that pioneer companies have many uncertainties in IPOs due to there isn¡¦t any information about offer price and proceeds to refer. When companies want to decide the appropriate offer price and proceeds, they have to spend a lot of time and money on information gathering. If there existed information spillover, and the information would be acquired from the other companies which had finished IPOs. Therefore, we try to research whether there existed information spillover in Taiwan IPOs market using 2SLS and Probit to analyze. By empirical results, there exist positive information spillover in offer pri!
ce and listing price revision. For underwriters, underwriter rank is based on underwriter reputation, and the underwriters which have better rank usually couldn¡¦t get the high initial return.
Keywords: Initial Public Offerings (IPOs), information spillover, underwriting reputation, Two-Stage Least Squares (2SLS)

Abstract: In modern cities, people generally have the desire to strike a proper balance between man and nature. This paper aims to discuss the method of using landforms in landscape design, particularly focusing on three functions of the landform: enclosure forming, viewpoint setting, and view setting. We selected Japanese gardens as case studies and adopted a three-layer model to classify a landscape design based on functions of the landform, site planning, and architectural planning. As a result, we have found some common methods of utilizing the unique landform characteristic to form an enclosed space and make viewpoints not to be seen, and to characterize various types of views, as a deep mountain view and a prospect view.

Abstract: In this paper, a rectilinear-based congestion-driven floorplanning algorithm is presented to enhance the wire congestion and the CPU runtime. The proposed algorithm contains two stages, including the simulated-annealing (SA) based approach with the concept of ant algorithm (SANTA) and the nonlinear programming based method. The objective of the first stage and the second stage are to minimize the multiple objectives, such as the area, wire length and wire congestion, and to further improve the wire congestion of the local congested region without the area overhead, respectively. First, the effective concept of the ant algorithm is integrated into the multiple objectives floorplanner, which simultaneously minimizes area, wire congestion and the total wire length, to speedup the runtime. Besides, the nonlinear programming (NLP) based formulations are provided to perform the module reshaping, which maximizes the common length between two adjacent congested modules. Fo!
r the floorplanner, the sequential-pair (SP) presentation is utilized to deal with the floorplan data at every iteration. For each iteration of the floorplanner, we first use SANTA to improve the neighbor searching and reduce the runtime. After performing the first state, we will obtain a floorplan with the objectives of the area, wire congestion and total length. For the intermediate floorplan, we select the two adjacent soft modules located at the most congested regions and divide the two soft modules into a set of connected sub-rectangles. Hence, we further reduce the congestion by enlarging the common boundary between the selected adjacent modules. Of course, the modular reshaping technique significantly increases the common length and the capacity of pins to reduce the wire congestion by utilizing the nonlinear programming based approach. To deserve to be mentioned that there is no area overhead after we perform the modular reshaping for the selected adjacent modules. !
Compared to the results of the traditional SA, SANTA achieves an avera
ge improvement on the area, the total wire length and CPU runtime by 3% and 8.1% and 23.0%, respectively. To show the superior to our approach, 30 floorplan samples are randomly selected from Microelectronics Center of North Carolina (MCNC) benchmarks. The experimental result shows that the reshaping method improves the wire congestion and total wire length by 22% and 1.54%, respectively.

Abstract: In recent years, scaling down device dimension or utilizing novel crystallization technologies provide the opportunity of applying much more devices to integrated circuit fabrication. Due to emerging DSM effects, the research about routing has drawn much attention in VLSI Physical Design. In this paper, we will focus on three issues. One, the traditional Manhattan routing has longer length and larger delay than XArchitecture routing. Second, in multilayer routing, the delay of one via is much larger than the delay of Manhattan routing. Third, since a routed segment and macro cell should be considered as obstacles, we must consider the rectangle and non-rectangle obstacles, and consider the number of vias as well. Our algorithm can handle both rectangle obstacles and non-rectangle obstacles, and we use fewer vias and X-Architecture router by region to construct the multilayer routing trees. The main purpose is to obtain an obstacles-avoiding routing tree of minimal !
wire length and minimal delay.

Abstract: This research presents an investigation into the numerical simulation of a flexible thin plate using Finite Difference (FD) and Finite Element (FE). Based on the FD method, an appropriate model of a thin plate was derived and its corresponding natural frequencies were estimated. Then, FE modeling of the plate system was implemented using the ANSYS software and the corresponding modes of vibration were computed by modal analysis. The obtained vibration modes for both models were then evaluated and compared. A number of attempts have been carried out to determine the nodal lines on the plate in order to identify the critical observation points for appropriate locations of the sensors using the FE simulation. Finally, the effectiveness of FD method for real time application was verified by comparative assessment of the obtained natural frequencies with the exact value reported by other researchers.

Abstract: ABSTRACT Virtual laboratory is a concept for monitoring/controlling experiments remotely via secure Internet/LAN/WAN/Wireless services and creating an environment for expert group discussion. It helps in better utilization of available instruments at different laboratories on sharing basis. Web enabling is the first step in this direction. Basic concept behind web enabling is to use 3-tier architecture of internet based software to provide remote access to critical machines. Creep Test laboratory has been used as test-bed for prototype implementation of this concept. Development of a prototype hardware/software suite including a web interface enables these machines to control/monitor remotely. A set of web-cams is installed for real-time physical monitoring of the experiment. The same information with periodic updates and status can also be accessed in condensed form on-demand via handheld devices, using GSM/GPRS Network. User alerts or notifications can also be !
disseminated through SMS. The ultimate goal of this project is to create a virtual laboratory where all sites can interact with one another and share information and expertise. The resulting increase in data exchange and analysis will bring about an improvement in the quality of research at all sites.

Abstract: Metallizing process has known a continuous extent, lately, because of the sprayed coatings' intensive application into various industrial fields. Metallized coatings have very important wear or, corrosion resistance characteristics and, when used for repairing worn parts, the prescribed surface quality specifications can be obtained only by grinding, after thermal spraying. Statistic models of grinded surface roughness are useful, specially, for optimizing the machining process. For adequate and, faster measurements, a LabVIEW data acquisition system was used to obtain grinded surface roughness values and, for obtaining statistical models needed, specialized regression soft-ware was considered.

Abstract: Development in the post-industrial landscape is one of many contexts that designer's will be forced to participate in as contributors to a sustainable future. The rapid expansion and globalization of industry over the past century has had a profound impact on industrial areas all over the world. A changing global economic and energy paradigm from industry to technology has and will continue to produce a vast landscape of obsolete industrial facilities. These facilities and their surrounding service industries are often strategically located near waterways, cities, and great centers of population, while simultaneously being segmented from the very people and communities that support their existence. The question then, for today's designer, is how to plan for the future of these post-industrial landscapes facing the new growth management paradigm. The re-use of postindustrial sites in order to develop multifunctional landscapes, as opposed to the consumption of previ!
ously undeveloped land is seen as a great possibility to the achievement of the new growth management paradigm – the accomodation of economic development and population growth while sustaining the spirit of community and the physical environment. To demonstrate the relevance of the reclamation of these sites, and a design approach that considers environmental, social, and economic aspects, this paper presents and analyzes two postindustrial reclamation studies. One located in Cleveland, Ohio, United States of America, (West 3rd Street Peninsula) and the other in Lagoa, Portugal (left margin to the Arade River), both presenting a vast potential for redevelopment. The main objective of this article is to show the post-industrial landscape as a complex resource, which can be recovered, re-used, and reintegrated into the surrounding community as a multifunctional landscape; a diverse environment that provides economic, social, and environmental benefits for the community and th!
e land- investigating the benefits that may arise from the reclamation
of urban postindustrial environments using a multifunctional cluster approach -. Additionally, the theory of the overall design strategy is discussed in detail in a manner such that it can be used as a resource for other designer's for non site-specific challenges.

Abstract: The last decades have seen a rapid change in attitudes towards the environment, which reflects a greater environmental awareness of environment amongst professionals as well as the general public. Public participation has become increasingly more important, playing a relevant role in determining the way society will manage, protect and reclaim the environment. This trend is "now" recognized by landscape architects, landscape ecologists, and sociologists, among others. A wide range of methods have been established all over the world, including new ways of people interacting, new types of events, new services and new support frameworks. This paper addresses the benefits of using public participation in the reclamation of post-industrial landscapes, and the ways in which the introduction of public opinion can improve the design process. Although public participation has gained wide acceptance among private and public domains, academic literature and research offers st!
ill limited understanding on how to accomplish it and what contributes to its success. The relevance of public participation is discussed through exploring the definitions of public participation, why the public should be involved and the role of participation in project acceptability. Using a best practice approach, this article discusses the use of public participation in the re-development of a post-industrial landscape, Emscher Park, located in the Ruhr Region, Germany. This case is selected to explore contributions to achieve sustainable development and the reasons why public participation should be an integral part of post-industrial landscape reclamation. We conclude that public participation may encourage awareness of "belonging to" a community, sharing common culture and creating identity. It improves community consciousness and responsibility while fostering a "collective sense". These are "feelings" of considerable importance in the development of new, satisfying!
and concerted projects.

Abstract: The concept of cultural heritage has clearly meant different things to different groups of scholars and the public interested in reclaiming traditions and cultural landscapes. Changes associated with urban growth often involve the destruction of built characteristics and natural elements, eradicating the physical expression of former indigenous ways of life that are a very important part of people's culture. This fact was particularly evident after the Second World War, when industrial landscapes faced deep transformations that in several cases contributed to its dereliction and to the disappearance of numerous industrial values, commonly known as industrial heritage. This phenomenon added to the necessity of reusing abandoned industrial landscapes in detriment of consuming new ones, increases the need to enlarge the interpretation of the term "cultural heritage", to analyse and interpret the value and significance of post-industrial landscapes and to develop new m!
echanisms to preserve it. Furthermore, it is increasingly acknowledged that the values connected with culture and heritage are highly significant for people's lives and need to be identified and highlighted. This paper presents a set of design principles that will be applied to the post-industrial landscape of left margin to the Arade River. These principles describe in a general manner the ways in which relevant resources created and deposited by the industrial society can be enhanced and how they can best be reclaimed and used.

Abstract: Adequate information about the existing landscape and about the nature of places that it is desirable to create and to experiment, can no longer be the result of superficial approaches based exclusively on designers and planners' ideas. Even if, planning and monitoring programs frequently use remote sensing data, focusing on changes in land cover and land use in relation to values such as biodiversity, land capability and recreation, they often neglect landscape aesthetics and culture. Aesthetics, a concept developed by the western civilization, has been a subject of debate for philosophers and artists, from the time of the ancient Greece, and more recently for architects, urban and environmental managers and even policy makers. In the present study a quantitative landscape assessment method was used in order to estimate visual impact, landscape quality, landscape fragility and visual absorption capability of a planned golf course which will be implemented in a for!
est landscape in the Algarve. The Study area is an enclosed, meadow, riverside landscape in Loulé, Portugal. Numerical values were used to assign factors such slope, vegetation observation distance, visual magnitude and human activities in order to analyze, evaluate and characterize the landscape. Geographic Information Systems (GIS) were used in order to understand and manage the visual resources and to mitigate the visual impacts that may arrise from the implemetation of the proposed golf course development.

Abstract: Montado ecosystem in the Alentejo Region, south of Portugal, has enormous agro-ecological and economics heterogeneities. A definition of homogeneous sub-units among this heterogeneous ecosystem was made, but for them is disposal only partial statistical information about soil allocation agro-forestry activities. The paper proposal is to recover the unknown soil allocation at each homogeneous sub-unit, disaggregating a complete data set for the Montado ecosystem area using incomplete information at sub-units level. The methodological framework is based on a Generalized Maximum Entropy approach, which is developed in thee steps concerning the specification of a r order Markov process, the estimates of aggregate transition probabilities and the disaggregation data to recover the unknown soil allocation at each homogeneous sub-units. The results quality is evaluated using the predicted absolute deviation (PAD) and the "Disagegation Information Gain" (DIG) and shows ver!
y acceptable estimation errors.

Abstract: Development in the post-industrial landscape is one of many contexts that designer's will be forced to participate in as contributors to a sustainable future. The rapid expansion and globalization of industry over the past century has had a profound impact on industrial areas all over the world. A changing global economic and energy paradigm from industry to technology has and will continue to produce a vast landscape of obsolete industrial facilities. These facilities and their surrounding service industries are often strategically located near waterways, cities, and great centers of population, while simultaneously being segmented from the very people and communities that support their existence. The question then, for today's designer, is how to plan for the future of these post-industrial landscapes facing the new growth management paradigm. The re-use of post-industrial sites in order to develop multifunctional landscapes, as opposed to the consumption of!
previously undeveloped land is seen as a great possibility to the achievement of the new growth management paradigm – the accomodation of economic development and population growth while sustaining the spirit of community and the physical environment. To demonstrate the relevance of the reclamation of these sites, and a design approach that considers environmental, social, and economic aspects, this paper presents and analyzes two post-industrial reclamation studies. One located in Cleveland, Ohio, United States of America, (West 3rd Street Peninsula) and the other in Lagoa, Portugal (left margin to the Arade River), both presenting a vast potential for redevelopment. The main objective of this article is to show the post-industrial landscape as a complex resource, which can be recovered, re-used, and reintegrated into the surrounding community as a multifunctional landscape; a diverse environment that provides economic, social, and environmental benefits for the communi!
ty and the land- investigating the benefits that may arise from the re
clamation of urban post-industrial environments using a multifunctional cluster approach -. Additionally, the theory of the overall design strategy is discussed in detail in a manner such that it can be used as a resource for other designer's for non site-specific challenges.

Abstract: The last decades have seen a rapid change in attitudes towards the environment, which reflects a greater environmental awareness of environment amongst professionals as well as the general public. Public participation has become increasingly more important, playing a relevant role in determining the way society will manage, protect and reclaim the environment. This trend is "now" recognized by landscape architects, landscape ecologists, and sociologists, among others. A wide range of methods have been established all over the world, including new ways of people interacting, new types of events, new services and new support frameworks. This paper addresses the benefits of using public participation in the reclamation of post-industrial landscapes, and the ways in which the introduction of public opinion can improve the design process. Although public participation has gained wide acceptance among private and public domains, academic literature and research offers s!
till limited understanding on how to accomplish it and what contributes to its success. The relevance of public participation is discussed through exploring the definitions of public participation, why the public should be involved and the role of participation in project acceptability. Using a best practice approach, this article discusses the use of public participation in the re-development of a post-industrial landscape, Emscher Park, located in the Ruhr Region, Germany. This case is selected to explore contributions to achieve sustainable development and the reasons why public participation should be an integral part of post-industrial landscape reclamation. We conclude that public participation may encourage awareness of "belonging to" a community, sharing common culture and creating identity. It improves community consciousness and responsibility while fostering a "collective sense". These are "feelings" of considerable importance in the development of new, satis!
fying and concerted projects.

Abstract: Zero-order hold devices (ZOH) are mainly used in digital control applications to obtain the output analog signals of digitally implemented controllers. However, it is proved that special hold devices such as the fractional order hold device (FROH) can improve, if properly tuned, the performance of hybrid control systems. Although the applicability of these devices has been theoretically studied in numerous works, there is no report of real experimentation with digital controllers that include special hold devices for the control signal interpolation. This lack of real application experiments is mainly due to the difficulties encountered in implementing such hold devices with the processing speed and configurability that real-time digital controllers require. This paper describes a totally configurable digital design of a FROH device, adequate for any digital control system platform. The implementation of an 8-bit resolution FROH prototype has been carried out and i!
ts performance tested on a field programmable gate array (FPGA).
